VOLGOTT, OF MARLBOROUGH, MASSACHUSETTS.

` LASTING-MACHIHNE.

Speciiication forming part of Letters Patent No; 39,870, dated September 8, 1863.

To all whom it may concern:

Be it known that I, TRUMAN WoLco'rT, of Stowe, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Lasting-Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this speciiication, in which- Figures l and 2 are plans or top views of my invention, the ring on the top of the machine being removed in Fig. 2; Fig. 3, a vertical section of the same, taken in the line a', Fig. l; Fig. 4, a detached perspective view of one of the slides and crimping-blocks pertaining to the same.

Similar letters of reference indicate corresponding parts in the severa-l figures.

This invention relates to a new and iinproved machine for adjusting uppers on lasts, as hereinafter. fully shown and described, whereby the work may be done in a superior manner and very expeditiously.

To enable those skilled in the art to fully understand and construct my invention, l will proceed to describe it.

A represents an upright framing, which may be constructed in any proper manner to support the working parts ofthe machine; and B is a treadle, which is secured in the lower part of the framing, and has a weight, G, on one end of it, as shown clearly in Fig. 3. This treadle B has a vertical rod, D, connected to it, said rod extending upward a sui table distance. The use of this rod will be presently shown. On the upper part of this framing A there is a circular plate, E, which has a number of radial grooves made in it to receive slides F, which are allowed to work freely in their grooves,and llave vertical pins a near their outer ends, on which friction-rollers b are placed, said friction-rollers being tted within slots c, which are made eccentrically in a ring, G, placed on the circular plate E in such a manner that it may turn freely thereon. By turning this ring G the slides F will be moved inward and outward from the center of plate E in consequence of the friction-rollers b fitting within the eccentric slots c of the ring G. This will be fully understood by referring to Figs. l and 2.

'.110 the inner ends of six of the slides F there are secured adjustable crimping-bars, which are designated by d d, e e, f f. The bars d d are opposite each other, and have their outer or faced sides curved to conform to the shape ofthe sides of the last, while the bars e e a-re curved ,to conform to the heel and the bars j' f to conform to the toe of the last. Two of the slides have hooks g g attached to them, and a hook, h, is attached to the plate B between the bars ff. The hook h is somewhat elastic or yielding, and to the inner ends ofthe slides F, which have the toe-bars f attached, there are secured elastic plates t' i, one to each. The hooks g g, it will be seen by referring to Figs. l and 2, are between the bars d d and e e. To the upper surface of each crimping-bar there is attached a metal plate, j, the inner edges of which project slightly over or beyond the inner or face sides of the crimping-bars.

The operation :is as follows: The upper is placed on the last, its front part drawn over the toe ofthe same by means of pinchers, and secured oy a peg. The last, which is shown in red, is then inverted and secured to the upper end ofthe rod D in any proper way. The opera-tor then depresses the elevated end of the treadle B, and thereby draws down the last, the central part of the plate F having an oblong opening, lc, made in it to receive the last, the sole of which is brought down just below the plates j of the crimping-bars. The operator then turns the ring G sufficiently to cause the hooks g g to grasp the shank of the last and adjust it in proper position, the toe of the last being properly retained and held by the elastic plates t' t' and hook h. These plates and hook constitute an important feature of the invention, as they insure a proper adjustment of the last and retain it when properly adjusted. When the last is thus adjusted, the operator removes his foot from the treadle B and turns the ring G so as to force all the crimping-bars d d, c @,ff inward and the upper will be snugly drawn or tted to the last, the plates j forcing the edge of the upper over the edges of the sole of the last, and the former is then pegged to the latter. By having two toe-crimping bars, f j', and two heel-crimping bars, e e, the work is done much better than it can be done with one of each only. When the ring G is turned so as to throw outward the crimping bars and hooks l ATENT J Carien.-`

g g, and the last is released, the Weight C will throw up the rod` D to its original position.

The ring G may be operated by gearing, if desired.

I do not claim thev sliding crimping-bars, broadly, or irrespective of their arrangement and the manner :in which they are operated, for such device has been previously used; but

I do claim asl new and desire to secure by Letters Patent- 1. The heel, side, and toe crimping bars d d, e e, ff, with plates j attached, arranged as shown, and operated by the ring G, provided with eccentric slots c, in Which pins or friction-rollers on the slides F are fitted, substantially as and for the purpose set forth.
